For Your Garden - November 2017

Native plants provide beauty as well as food and shelter for wildlife. Native species are adapted to the Illinois climate. They require little or no watering and are resistant to drought, insects and most diseases. Because they are perennials, you can welcome their presence year after year.

late boneset (Eupatorium serotinum)

Late boneset, also known as late-flowering thoroughwort, can be found throughout Illinois in pastures, along roads and in woodlands. It flowers from July through October, making it an important nectar source for pollinators late in the year. The flowers are white and develop in small, branched clusters at the stem tip. The leaves are mostly paired along the stem. The plant reaches a height of about four feet.  

Classification and taxonomy are based on Mohlenbrock, Robert H. 2014. Vascular flora of Illinois: A field guide. Fourth edition. Southern Illinois University Press, Carbondale. 536 pp.
